The proper management of bleeding risk in patients undergoing percutaneous coronary intervention (PCI) is critical. Recently, the Academic Research Consortium for High Bleeding Risk (ARC-HBR) criteria have been proposed as a standardized tool for predicting bleeding risk. We sought to compare the predictive performance of ARC-HBR criteria and the PRECISE-DAPT score for bleeding in Korean patients undergoing PCI. We recruited 1418 consecutive patients undergoing PCI from January 2012 through December 2018 (Dong-A University Medical Center, Busan, Korea). The ARC-HBR and PRECISE-DAPT scores showed a high AUC for three bleeding definitions (AUC 0.75 and 0.77 for BARC 3 to 5, AUC 0.68 and 0.71 for TIMI minor to major, AUC 0.81 and 0.82 for GUSTO moderate to severe, respectively) and all-cause death (AUC 0.82 and 0.82, respectively). When compared with the ARC-HBR score, the discriminant ability of the PRECISE-DAPT score was not significantly different for bleeding events and all-cause death. The ARC-HBR criteria and PRECISE-DAPT scores demonstrated reasonably good discriminatory capacity with respect to 1-year bleeding events in Korean patients treated with DAPT, regardless of the bleeding definition. Our findings also suggest that the simple PRECISE-DAPT score is as useful as ARC-HBR criteria in predicting bleeding and all-cause death after PCI.

Embedded System operates hardware installed like processor, memory device, various input/output devices and software to control them.

The demonstration project of the electrical grid for Smart grid is progressed, the smart digital appliances AV technology, Smart home energy management technology charging the management function of complex energy for the automation management of air conditioning and heating, humidity and air, the health care technology charging the design of housing for the elderly and disabled and the measurement of individual bio information, and the Smart home security technology dealing with the biometric security and motion sensors, etc. have been studied. The power monitoring terminal which uses a variety of wired and wireless networks and protocol is the target additionally to be considered in addition to the security vulnerabilities that was occurred in the existing terminal. In this research paper, the author analyzes the cryptographic techniques corresponding to the smart meter occurred by the problems that are exposed on the outside which are vulnerable to physical attacks, and intends to propose the design of the security systems for the Smart meter terminal being able to maximize the efficiency of the terminal.

This paper presents an implementation of embedded platform based ARM A8-cortex processor for android supporting. The development board for S5PV210 is a platform that is suitable fo r code development of SAMSUNG's S5PV210 32bit RICS micro controller(ARMv7) architecture for hand-held device and general applications. Embedded platform development board offers various function and high efficiencies. In addition to the high performance, the embedded platform offers low current consumption, ensuring low costs and power.

Although optical fibers can provide an enormous bandwidth of several tens of THz in the low-loss transmission region, single channel transmission speeds are limited to less than a few tens of gigabits per second due to the speed limit of optoelectronic components used. Therefore, wavelength division multiplexing (WDM) technologies utilizing the fiber bandwidth more efficiently and economically are actively pursued for both optical links and optical networks applications. Optical add/drop multiplexer (OADM) has been considered as one of the key components used for selectively dropping/inserting wavelength channels from/into WDM networks. We propose a tunable OADM using a fiber-optic tapped delay-line transversal filter to provide the flexibility in the WDM network configuration.

Background: Adrenocortical carcinoma (ACC) is an extremely rare tumor. Its early detection is difficult and its prognosis is poor. Method: We retrospectively analyzed the medical records of 13 patients with ACC between 1995 and 2005 at Samsung Medical Center. Their clinical features and prognosis were evaluated. Results: The average age of the patients with ACC was 40 years (2~75 years). Eight patients were men and five were women. On the first visit, eight of 13 patients (62%) complained abdominal pain, and abdominal mass was palpable in five of 13 patients (38%). Urinary concentration of 17-ketosteroid collected for 24 hours was increased in two of eight patients (25%). Three out of 13 patients were identified as having functioning adrenal tumors (1 Cushing's syndrome and 2 androgen-producing tumors), and the other 10 patients had hormonally inactive adrenal tumors. Ten patients had tumors in left adrenal gland, and three had in right adrenal gland. At the time of diagnosis, four patients were cla ssified as having stage II, seven as stage III, and two as stage IV. Twelve patients underwent adrenalectomy. One of them received additional chemotherapy, and two patients were treated with external radiation therapy after surgery. The other one patient was treated only with chemotherapy due to the presence of liver metastasis. It was possible to continue the regular follow-up in eight of 13 patients. The median duration of follow-up was 39 months (7~114 months). Six of them are still alive (three have no evidence of disease, one had persistence of disease, and two had recurrence of disease during follow-up period). Two patients died of multiple metastases and lung metastasis, respectively. Conclusion: Radical surgery is the only curative approach and is recommended for all patients with resectable tumors, even though in those patients with recurrent disease. There is no consensus concerning adjuvant therapy (J Kor Soc Endocrinol 21:47~52, 2006).

Background: Octreotide (OC)-LAR is a long-acting preparation of octreotide which has been effectively used to suppress GH/IGF-1 hypersecretion in acromegalic patients. The clinical response, biochemical outcomes, and safety of OC-LAR were evaluated in 27 active acromegalic patients. Method: 27 patients with an active disease status (according to the clinical picture, GH >5 μg/L and elevated age-matched IGF-1), and previously treated with bromocriptine after surgery, comprised the study population. OC-LAR was given (20 mg, i.m., every 4 week for 3 injections, then the doses were titrated individually) and the acromegalic symptoms and adverse reactions recorded. The serum levels of GH and IGF-1 were evaluated every 12 week. The acromegalic symptoms including headache, fatigue and arthralgia, improved in all patients. Results: Gastrointestinal side effects were transient and mild. The levels of GH significantly decreased, from 8.9 ± 3.5 to 2.9 ± 2.2 μg/L at 12 weeks (P < 0.001, vs. baseline), to 2.9 ± 2.1 μg/L after 24 weeks (P < 0.001) and to 2.5 ± 1.3 μg/L at 48 weeks (P < 0.001). The levels of IGF-1 significantly decreased, from 753.7 ± 213.6 to 429.7 ± 253.4 μg/L at 12 weeks (P < 0.001, vs. at baseline), to 405.7 ± 213.3 μg/L at 24 weeks (P < 0.001) and to 348.9 ± 144.7 μg/L at 48 weeks (P
